Detailed Description
The utility model is further explained by the following specific embodiments:
as shown in fig. 1, the present embodiment provides a roller mill, which comprises a frame 10, a fixed grinding roller 20 rotatably connected to the frame 10, a swing arm 30 rotatably connected to the frame 10 at one end, a movable grinding roller 40 rotatably connected to the swing arm 30, a dual output shaft reducer 50 mounted on the frame 10, a height adjusting device 60 mounted below the dual output shaft reducer 50, and a driving motor 70 mounted on the height adjusting device 60, wherein the movable grinding roller 40 is located above the fixed grinding roller 20, and the movable grinding roller 40 abuts against the fixed grinding roller 20. Of course, the roller mill provided in the present embodiment further includes a control system for controlling the operation timing of the driving motor 70, and the control system is a conventional system and is not a focus of the present embodiment, and will not be described in detail here.
The frame 10 comprises a bottom frame 11 and a top frame 12 fixedly connected above the bottom frame 11, and the bottom frame and the top frame are fixedly connected through bolts, so that the frame is convenient to disassemble and transport. Specifically, the bottom frame 11 has more than four lower vertical columns 13, the top frame 12 has upper vertical columns 14 which are matched with the lower vertical columns 13 one to one, flanges are arranged at the lower ends of the upper vertical columns 14 and the upper ends of the lower vertical columns 13, and the two corresponding flanges are locked by bolts to realize the fixed connection between the bottom frame 11 and the top frame 12. Preferably, an adjusting plate (not shown) is provided between the bottom frame 12 and the top frame 12, and in particular, the adjusting plate is provided between two flanges locked by the same set of bolts. In addition, an air spring 80 matched with the swing arm 30 is arranged on the top frame 12, and the air spring 80 is positioned above the suspended end of the swing arm 30 and used for limiting the upward swinging distance of the swing arm 30 so as to avoid the influence on the crushing effect caused by the overlarge distance between the fixed grinding roller 20 and the movable grinding roller 40. When the pneumatic sand crusher is used, the height of the top frame 12 can be adjusted through the number of the adjusting plates clamped between the two flanges locked by the same group of bolts, and then the height position of the air spring 80 is adjusted to control the particle size of crushed sand.
Two output shafts of the double-output shaft speed reducer 50 and two ends of the movable grinding roller 40 are respectively connected with a transmission chain 51 or a transmission belt in a one-to-one correspondence mode, and therefore single-side stress of the movable grinding roller 40 can be effectively avoided. The fixed grinding roller 20, the swing arm 30, the double output shaft speed reducer 50 and the driving motor 60 are all connected to the base frame 11, and one end of the swing arm 30, which is rotatably connected with the base frame 11 of the frame 10, and the double output shaft speed reducer 50 are located on the same side of the movable grinding roller 40, so that the swing angle of the swing arm 30 can be ensured to be lifted as much as possible under the condition that a transmission chain 51 or a transmission belt is not damaged.
A driving chain or a driving belt (not shown) is connected between the output shaft of the driving motor 70 and the input shaft of the dual output shaft reducer 50, the tension of the driving chain or the driving belt is adjusted by the height adjusting device 60, and certainly, when the driving chain or the driving belt is replaced, if the size and the specification of the newly replaced driving chain or driving belt are not consistent with those of the replaced driving chain or driving belt, the driving chain or the driving belt can be matched by the height adjusting device 60. The height adjusting device may be a conventional device, such as an electric lifting platform or a jacking cylinder, and preferably, in this embodiment, the height adjusting device 60 includes a movable plate 61 with one end rotatably connected to the frame 10 and an adjusting rod 62 screwed on the movable plate 61, the adjusting rod 62 may be directly screwed on the movable plate 61 or indirectly screwed on the movable plate 61 through a nut, the lower end of the adjusting rod 62 abuts against the frame 10, and the driving motor 70 is installed on the movable plate 61 and is located between the end of the movable plate 61 connected to the frame 10 and the adjusting rod 61. Thus, the height position of the driving motor 70 can be adjusted by rotating the adjusting lever 62 to adjust the placing angle of the movable plate 61.
Preferably, the frame 10 is further provided with a feeding device 90, and the feeding device 90 can be a feeding device 90 used in a conventional roller mill, which is not the focus of the embodiment and will not be described in detail herein. In addition, a current detecting device (not shown) for controlling the feeding speed of the feeding device 90 is provided on the driving motor 70, and of course, both the feeding device and the current detecting device are connected to the control system in communication.
When the automatic stone feeding device is used, the stone net feeding device 90 is conveyed to the position right above the fixed grinding roller 20 and is extruded into the position between the movable grinding roller 40 and the fixed grinding roller 20 under the driving of the movable grinding roller 40, the stone net feeding device is crushed under the pressure action of the movable grinding roller 40 and the fixed grinding roller 20 and naturally drops under the action of gravity, and in the process, the movable grinding roller 40 can swing upwards under the counter-acting force and extrude the air spring 80 to ensure that stone can enter the position between the movable grinding roller 40 and the fixed grinding roller 20. When too much stone or too hard stone enters the space between the movable grinding roller 40 and the fixed grinding roller 20, the load of the driving motor 70 is increased, the input current of the driving motor 70 is increased and is detected by the current detection device, and the current detection device sends a signal to the feeding device 90 through the control system to control the feeding device 90 to reduce the feeding speed; of course, when the load is reduced, the input current of the driving motor 70 is reduced, and at this time, the current detecting device sends a signal to the feeding device 90 through the control system to control the feeding device 90 to increase the feeding speed.
The present invention has been described in detail with reference to the accompanying drawings, but the embodiments of the present invention are not limited to the above embodiments, and those skilled in the art can make various modifications to the present invention according to the prior art, and these all belong to the protection scope of the present invention.
